To all whom it may concern.-

Be it known that I, JOHN W. WATKINS, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Sheet-Metal Window-Sashes, whereof the following is a specification, reference being hadto the accompanying drawings.

My invention relates to sheet-metal window-sashesw ch are divided by munnions and muntins into separate panes, and more particularly to the means for supporting the muntins in such sashes. i While the word munnion is frequently used as a name for the bars, whether horizontal or vertical, by which the sash is divided. into panes, yet in this specification and in the claims for the sake of more accurate distinction I will use the words in what I understand to be their strict technical sense, in which the word munnion is confined to the vertical bar'or bars and the word muntin Hitherto in sheet-metal Window construction ithas been customary to build the sash.

the sash. The muntins for the further horicreated have been arranged to fit snugly against the opposing edges of the side rails or munnions, but have not. been permanently secured thereto, being left movable in order that when the glass for the lower pane has been inserted the muntin may be laid above said pane and then another pane slid into the grooves on top of this, and so on. There is an advantage in such construction resulting in some saving -of glass, since small differences in the vertical height of the pane may be disregarded and will adjust-themselves in I utting together the entire'saslL There is, however, a disadvantage resulting from the failure to permanently secure the muntins in the fact that if left unsecured upon the breaking or melting of a lo'wer'pane the removal of the support for the muntin above it allows it to slide down with the anes above it, usually occasioning further amage. My invention is directed toward the overcoming of this 'difficuty without the loss ofthe advantage of the separable construction and provides a simple means by which the muntins may be adjustably secured in any desired p0 siti on accordin to the height of the pane beneath them, at %he same time providing a suf ficiently firm support at each end of the.

muntin to prevent its falling when the pane below is broken or burned out.

I have shown in'the accompanying d1awings a number of modifications of which my invention is'susceptible, all of which, however, have this in common: They have a wire or strip or other support secured to the sash bentin such. form as t9, support the muntin above the underlying pane.

In the accompanying drawings, Figure I is a front elevational view of a sheet-metal window-sash arranged to conveniently embody various forms of my invention. Fig. II is a horizontal sectional view of a munnion, taken on the line II II in Fig. I, showing the integral supporting-piece slitfrom the webs which form the bottom of the grooves and bent to form horizontal muntin-supports. Fig. III is a horizontal sectional view of a tide rail, taken on the line III III in Fig. I, showing the integral supporting-piece slit from the side wall of the groove and bent to form a horizontal support. tical sectional view taken on the line IV IV in Fig. II. Fig. V is a vertical sectional view taken on the line V V in Fig. III. Fig. VI is a horizontal sectional view of the munnion similar to Fig. II, showing a separable supporting-piecein the form of a sheet-metal strip passing through the munnion and upturned at its extremities to engage the muntins- Fig.

Fig. XV is a vertical sectional view taken on the line XV XV in Fig. XIV. Fig. XVI is a perspective view broken in the middle of the sup orting-piece shown in Figs. XIV and XV. igs. XVII to XXII are detail perspective views of difl'ering forms of supporting strips or wires embodying my invention. v

In Figs. I to V, I have illustrated my invention in a simple form. 1 is a windowsash comprising the side rails 2, the bottom rail 3, and themeeting-rail 4. 5 is a munn'ion, and 6 6 are muntins- InFig. II is shown a horizontal section of this munnion with the panes fitting its grooves on either side. It will be observed that this'munnion is shown as formed by the bending and interlocking of two pieces of pane-groove sheet metal, so as to form the two panegrooves with a thin partition between them, and the union of the two parts is efl'ected by the interclenching of the projecting webs of the two parts by which the partition between the pane-grooves is formed. This construction forms no part of my present invention, as it forms art of a previousIy-filed application. It will )e understood that my present invention is applicable to sheet-metal sashes generally irrespective of the method by which the parts are put together. Before the glass .is inserted in the sash flaps 7 7 are cut in the web which forms the outside ofjthe partition between the grooves. These flaps are capable of being bent down to a varying depth, according to the size of t? panes. When the two lower panes have been inserted, (for which purpose the meeting-rail may be providedwith a slot,) the laps 7 7 are bent down over the top of the panes. I have shown the flaps only in connection with the munnion; but it will of course be understood that asirnilar fiap is 'cut into and bent down from the oi theside rails of the sash. The muntins are then slid down on top of the panes resting upon the bent out flaps, and the up er panes are then slid into place and the sac completed. If now a lower pane be broken out, the flaps at either end of the muntin will support it from falling notwithstanding the absence of the pane below it.

In Figs. III and V a similar construction is shown, except that the flap 8 different shape, and instead of being bent out from the partition between the grooves it is cut into and bent out from one of the side is of a slightly walls of the pane-groove. I have illustrated the flap here in connection with the side rail of the window; but it will be understood that flaps are to be cut in'the munnion.

In Figs. VI to IX, I have illustrated a construction n which in the place offlaps cut from the pane-grooves there are employed separate strips bent so as to engage the muntin or the side rail and projected to pass below the muntin and en port it.

In Figs. VI and VII ,5 is the munnion. At

a point near where the junction with the muntins is expected to take place the partition between the pane-grooves is pierced with an aperture 10, and through this is inserted a flat metal strip 1 1. (See Figs. XVII to XIX.) This strip is notinserted until the lower panes have been put in place. It is then passed through the aperture, and unless the aoerture 1O coincides precisely with the top 0 the panes it is bent until it reaches to the top of the pane; It is then bent out along the top of the pane, taking the shape shown in Fig. XVII. When the muntin is slid down over the pane, it rests upon the projecting portions of the strip. If desired, the extremities may be bent upward again, as shown'in Figs. VI, VIII, and XIX, and the muntin provided with holes 12, into which its bent ends enter andover which they may be clenched. Itwill be thusseen.

that by this simple device the muntins are firmly locked to the munnion on each side. In Fig. XVIII the strip 19 is shown in the shape which it assumes when the aperture 10 coincides with the top-of the panes.

In Figs. VII, IX, and XXI, I have shown a similar strip applied to the side rail of the sash. Here the entering end of the strip 17 is bent up and down, and after passing through the aperture 13 in the bottom wall of the pane-groove is drawn so as to clench within it. The external portion of the strip is then bent along the pane-groove until it reaches the top of the pane. It is then bent out along the edges of the pane and passed up through a hole 12 in. the muntin and may be clenched, as shown. In Figs. X .toXIII, I have shown a similar construction, except that is employed instead of the strip 11. Thus, referring to Figs. X and XII, a hole 14 is pierced through the munnion and the wire 15 inserted in the-hole and bent on either side until it reaches the top of the lower panes and then bent out, so as to'aii'ord a support for the muntins. v

Figs. XI XIII, and XXII illustrate a similar wire 18 applied to the side rail passing through an aperture 16 and being clenched within the rai and also bent down along the groove to the top of the pane as before.

In Figs. XIV to XV I-,*I have illustrateda slightly-difiering construction, in which instead of separate wires or strips at either side a simple bent wire are intended to be cipleto wit, a supportingpiece forthcof the pane a single wire is caused to engage the pane-groove on both sides and is stretched across underneath the muntin and supports it. This is a stronger construction than the others and may be employed where the panes are very large or the glass very heavy. In Figs. XIV and XV, 5 is the munnion, and 2 the side rail. The pane-grooves of both of these are pierced to receive the wire 20. This wire enters these apertures, and thus engages both the pane-grooves at its extremities near the top of the loweixpa'ne and is immediately bent until it rests upon the top of the pane. The muntin when slid down upon it rests on the wire 20 instead of on the pane.

Having thus described my invention in several different forms, I desire '6 to be understood that it is ca able of much further variation and that the forms described by me but examples of some different ways of embodying it. Furthermore, under some circumstances two or more of the forms described by me may be'used inconjunction. Thus where a flap 8 bent from the side of the pane-groove is employed an auxiliary strip clenched upon the flap and also to the muntin, as, for example, shown in Fig.

IX, ma be employed. Other cornbinations wil also suggest themselves at once toone skilled in the art as carrying out my .in-

vention. In all there is a common prinmuntin either integral withor attached to the munnion (or the side rail, as the case may be) and capable of being accurately adjusted so as to pass under the muntiii to support it tin-support consistin in the up er position according to the size of the pane eloW it;
